Garrett Hedlund ("TRON: Legacy") has joined the Coen brothers' "Inside Llewyn Davis," adding to an already stellar cast of Carey Mulligan, Oscar Isaac, John Goodman and Justin Timberlake. Like Mulligan and Timberlake, Hedlund can sing (he was probably the best part of "Country Strong" – see below). "Inside Llewyn Davis" is about the 1960s Greenwich village folk music scene. Isaac played Mulligan's husband in this year's "Drive," and now plays real life folk singer Dave Van Ronk. Shooting is set to kick off this February in New York City.
